66. Which of the following formulas is used to determine the number of acres in a parcel of land?
Answer: D
The formula used to determine the number of acres in a parcel of land is square feet divided by 43,560.
To convert the area of land measured in square feet to acres, the area in square feet must be divided by 43,560, which is the number of square feet in one acre.
A) length × width
This formula is used to calculate the area of a rectangle but does not convert the area into acres. While it may provide the area in square feet, it does not yield the correct number of acres without further calculation.
B) square feet divided by 640
This formula is used to convert an area measured in square feet to square miles, as there are 640 acres in a square mile. Therefore, it is not the correct approach for determining the number of acres in a parcel of land directly from square feet.
C) square miles × 1,296
This option does not relate to the conversion between square feet and acres. It appears to be an incorrect formula, as it does not account for the relationship between square miles and acres properly, nor does it provide a method to convert square feet to acres.
D) square feet divided by 43,560
This is the correct formula to determine the number of acres in a parcel of land. Since one acre is defined as 43,560 square feet, dividing the total square footage by this number yields the area in acres.
Conclusion
The correct answer is option D, as it directly provides the necessary conversion from square feet to acres. Options A, B, and C fail to convert square feet to acres accurately, with A providing only area calculation and B and C addressing different conversions entirely.
